OPERATING MEANS FOR DOORS.

To all whom it may concern:

Be it known that JOHN Sol-101m, a citizen of the United States ofAmerica, residing at Davenport, in the county of Scott and State ofIowa, has invented certain new and useful Improvements in OperatingMeans for Doors, of which the following is a specification.

My invention relates to improvements in apparatus for opening, closingand fastening doors for garages and other structures.

The objects of my invention are, first, to provide an apparatus by theuse of which the driver of an automobile may open the doors of a garageto drive into it without getting out of his car and may close the doorsafter driving out of the garage, without getting out of the car; second,to provide an apparatus which will automatically lock the doors in openor closed position; third, to provide a simple, cheaply manufactured andeasily operated locking device adaptable for use upon doors and othermoving objects.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a top or plan view of a garage embodyingmy invention, but with the roof removed; Fig. 2 is a side elevation ofthe operating post; Fig. 3 is an enlarged detail of the lockingapparatus, showing a plan view thereof; Figure 4 is an edgev view of thelocking apparatus; Fig. 5 is a detail plan view of the locking apparatusshowing one 'of the bolts or latches retracted from its locked position;Sections AA and B-B, are cross-sections upon the lines AA and BB ofFigure 3, respectively.

My invention comprises links, 4, each of which has one end pivoted at 5to an operating lever, 6, and its opposite end pivoted in a suitablesocket, 23, secured to a door, 2, of the garage.

The operating lever, 65, is fulcrumed at 7 upon a suitable support, 7,which may be a timber secured to joists or rafters, 29, of the garage orin any other suitable manner. The support, 7 should be secured in aposition which would allow the travel of the pivot, 5, to occur as nearmidway of the garage from side to side as circumstances permit.

A semi-circular rack, 8, preferably of band iron or other suitablematerial, is secured to the support, 7 and provided with notches, 9 and10, adapted to receive and engage the inner ends of the bolts,11'and'12, respectively. Thejnotches, 10 and 9, are located at pointsupon the rack, 8,- which approximate the extreme travel of the lever, 6,so that when the doors. are fully open or fully closed, the notches, l0and 9, will engage the locking bolts, 11 and 12,-respectively.

A head, 25, is secured to the end of the lever, 6, oppositeto the pivot,5. The head provides bearings, 23 and 24, for the bolts,

.11 and 12. The lower end of the'bolts, 11

and 12, are preferably formed square, tofit in the square holes orsockets, 24 and prevent turning. The opposite ends of the bolts, 11 and12, are preferably round so as to slide readily in the openings, 23.

A compression spring, 22, is. mounted upon each of the bolts, 11 and 12,one end of which bears against the outer portion of the head and theother end of which bears against a shoulder formed upon the bolt so thatthe expanding action of the spring. will.

drive the bolts, 11 and 12, int-o their respective' notches, 10 and 9,when in proper position therefor.

An oscillating or rocker bar, 13, is pivoted to the head,-25, andprovided with an opening, 14, opposite the pivot to permit theattachment of an operating cable, 15., The ends of the oscillating orrockerbar, 13, are

provided with openings, 13*, to receive links,

11 and 12 respectively. The inner ends of these links are suitablysecured to the upper ends of the bolts, 11 and 12, and the outer endsare provided with heads, 21 and 20, to secure them to the oscillating orrocker bar, 13.

The lever, 6, is preferably formed of two iron bars, as shown in Figure4;

.A cable, 15, is secured to the osclllating or rocker bar, 13, by passinthrough the hole, 14, or, any other suitable method and passes over oraround a sheave or pulley,

16, secured on the side of thegarage and thence out through suitableopenings above the garage door to and over' pulleys, 17, suitablysecured to a post, 19, and down, and around a] second pulley, 18,secured to the post, 19, a suitable distance below the pulleys, 17.

In the operation of my device, when the doors are shut as'shown in solidlines in Figure 1, the left hand line of the cable shown in Figure 2,'is pulled downward;

This pulls the oscillating bar, 13, toward the pulley,- 16, and as theoscillating bar rocks on its pivot, it raises the link, 11 thus pullingthe bolt, 11, out of the notch, 10, and unlocking the doors. Thecontinued pull on the cable then carries the head and the end of thelever, 6, to Which it is secured, around to the position, shown indotted lines in Figure 1, and when it reaches that-position, the bolt orlatch, 12', drops into the notch, 9, and locks the doors in the openpos'itionand also looks the lever, 6-, against further movement towardthe pulley, 16;

This looks the doors against being blown shut by the Wind and the carcan then be driven into the garage safely. Upon driving the car out ofthe garage, the driver can pull the right hand cable as shown in Figure2, downward, which will reverse. the movement or the rope, unlatc-h thebolt, 12, from its notch, 9, carry the head of the lever, 6-, around tothe closed position. shown in solid lines in Figure 1 and as th bolt,11, drops into the notch, 10, it will lock the doors in closed positionand they will remain locked until released by again pnllingthe rope orcable, 15.

Short pieces of rope may be attached to the cable, 15, at appropriateplaces inside "of the garage, so that the doors can be opened or closed,from the inside oi the garage as well as from the outside and additionalmeans may be provided for locking the lever, 6, in the closed positionwhich can only be operated from inside the garage or the doors may besecured. by the ordinary hasp and padlock or other suitable means on theinside of the garage.

It is obvious that this device, with slight modifications, can be usedfor sliding doors, Which I have illustrated in an additional applicationfor patent which I filing in connection herewith and that this form oflever movement may be adapted to a considerable variety ofotherpurposes; also that he lockingandunlocking mechanism in say beapplied to a large variety o1 levers and utilized for many differentpurposes.

The form, size, proportions and position of the different parts of myinvention may be varied to suit the requirements each particular case asoccasion arises.
